Schizophrenia is a chronic and severe mental disorder that affects a person's ability to think, feel, and behave clearly. It is characterised by disruptions in thought processes, perception, emotional responsiveness, and social interactions. People with schizophrenia may seem like they have lost touch with reality.

The term "schizophrenia" does not mean "split personality" or multiple personality disorder. That is a common misconception. Instead, it refers to a fragmentation of mental functions.

Key Characteristics and Symptoms:

Schizophrenia typically involves a range of symptoms that are often categorised as:

1. Positive Symptoms (Psychotic Symptoms): These are symptoms that are "added" to a person's experience of reality. They include:

• Hallucinations: Experiencing sensory perceptions that are not real. The most common type is hearing voices, but hallucinations can involve any of the senses (seeing, smelling, tasting, feeling).
• Delusions: Holding firmly to false beliefs that are not based in reality. These can be paranoid (believing others are trying to harm them), grandiose (believing they have special powers or importance), or bizarre (beliefs that are highly implausible).
• Disorganised Thinking (Formal Thought Disorder): Difficulty organising thoughts logically, which can manifest in disorganised speech. This might include:
  • Loose associations: Jumping between unrelated topics.
  • Tangentiality: Answering questions in a way that is only vaguely related or completely irrelevant.
  • Word salad: Speaking in a jumbled or incoherent way, using real words that don't form understandable sentences.
• Disorganised or Abnormal Motor Behaviour: This can range from childlike silliness to unpredictable agitation. It can also include catatonia, a state of reduced responsiveness, which can involve a lack of movement or holding rigid or unusual postures.

2. Negative Symptoms: These refer to a reduction or absence of normal behaviours and emotions. They can significantly impact a person's ability to function in daily life and are often more persistent and harder to treat than positive symptoms. They include:

• Flat Affect (Blunted Affect): Reduced expression of emotions, such as a lack of facial expressions, a monotone voice, and reduced eye contact.
• Avolition: Lack of motivation or ability to initiate and persist in goal-directed activities (e.g., work, school, hobbies).
• Alogia (Poverty of Speech): Speaking less than usual and providing brief or empty replies.
• Anhedonia: Reduced ability to experience pleasure.
• Asociality: Lack of interest in social interactions and withdrawal from social relationships.

3. Cognitive Symptoms: These involve difficulties with thinking processes that can affect various aspects of cognitive function. They are often subtle but can significantly impact a person's ability to function independently. These include:

• Problems with working memory: Difficulty holding and manipulating information in mind.
• Difficulties with attention and concentration.
• Impaired executive functions: Problems with planning, organising, problem-solving, and abstract thinking.

Diagnosis:

A diagnosis of schizophrenia requires a comprehensive psychiatric evaluation. According to the DSM-5, the criteria include having at least two of the characteristic symptoms (including at least one of delusions, hallucinations, or disorganised speech) for a significant portion of time during a one-month period, with continuous signs of the disturbance persisting for at least six months. These symptoms must also cause significant social or occupational dysfunction and not be attributable to other medical conditions or substance use.

Causes:

The exact cause of schizophrenia is not fully understood, but it is believed to result from a complex interplay of genetic, environmental, and neurobiological factors. Research suggests that imbalances in certain brain chemicals (neurotransmitters), such as dopamine and glutamate, and differences in brain structure and function play a significant role.

Treatment:

Schizophrenia is a treatable condition, and management typically involves a combination of approaches:

• Medication: Antipsychotic medications are the primary treatment to reduce psychotic symptoms. These medications help regulate neurotransmitter activity in the brain. Both older (first-generation) and newer (second-generation or atypical) antipsychotics are used, and the choice depends on individual needs and side effect profiles.
• Psychotherapy: Various forms of talk therapy can help individuals with schizophrenia cope with their symptoms, manage stress, improve social skills, and adhere to their medication. Cognitive behavioural therapy for psychosis (CBTp) and social skills training are commonly used.
• Psychosocial Support: This includes a range of services aimed at helping individuals function in the community, such as supported employment, housing assistance, case management, and family support.
• Family Education and Support: Educating family members about schizophrenia and providing support can improve outcomes for both the individual with the disorder and their family.

Early diagnosis and consistent treatment are crucial for managing schizophrenia and improving the long-term outcomes for individuals living with this condition. While there is currently no cure, many people with schizophrenia can lead meaningful and productive lives with appropriate support and treatment.
